Trying out my camera...
Can clearly see gasket deformed.
What do you suppose the orange deposit on the plugs is...?
1, 5, 7 look interesting, they have grey deposit.

Some squeaky pulleys.
What's with the corrosion on the heater return, is this Dex-Cool related...?

Just my $.02...
The orange plug "stuff" is what I've seen on turbo Buick plugs that have had "octane booster" run in the fuel. [IE: 104, etc]
The gaskets and the heater nipple crud.. Could be that "wonderful" DEX doing it's work on gaskets..
I've seen many GM intakes eaten up at gasket surfaces w/ that crap.
[Daughter just got rid of an 02 grand Am w/ the intake gaskets eaten out...]
Does this engine have alot of miles on it? [Hers was @ 120K]. Her Subby did the same thing!
Seems to be considerable "chatter" about that stuff....

Hi Chuck,Originally Posted by Chuck L.
I occasionally put in a bottle of Techron...
See how the orange stuff is very localised, it's on the same location on plugs 2,3,4,6... what causes it to be localised...?
Yes, my Mrs took her 02 GA in for LIM gasket repair under warranty.
Subaru use Dex also...?
Yes, I have to figure out how to hold it steady and get it to focus properly.
From what I've read (high ECT+DethCool) = corrosion
I've not seen this (yet) but I've flushed a few times in the past & keep ECT around 200*F.

The location of the orange crud is likely due to the orientation of the plug in the exhaust gas flow pattern...
I'm dropping the Deathcool out of my 07 @ 50K miles, and 3 yrs of use. No point in tempting a visit from Murphy!! We all know he's alive and well!

A few months ago I noticed the hose on the steam crossover tube had orange gel on the edge of it, and I found the screw clamp was loose.
Then a few weeks ago the water pump gaskets let go, major coolant leakage (pump weep hole could never leak that much)... so I removed pump, hoses and crossover tube... I didn't see any gel build up anywhere, just a very thin coating of orange scum on edges of where hoses fitted... end of crossover tube was slightly corroded/gooped... rest of radiator and block passages appeared clean... made me think of the hoses/clamps only being 99.9999% air sealed (i.e. microscopic air leak)... Dex-Cool turned to goop at the hose interfaces in response to amount of air... does that sound plausible...??
The corrosion on heater return is scary/weird... did that have an air leak [pump suction was pulling air in] (I didn't see any coolant leaking)...?
If that continued corroding then pretty soon the hose would not have been able to seal.
Yes, this was a door knock by Murphy but he didn't stay long enough for me to open the door... I replaced with Prestone All...
I just don't believe the statements "Dex-Cool will not corrode/goop if..."... the if part just isn't reasonable in the real world...
Hmmm, some people are still defending Dex-Cool in the face of complaint history... (did you see the youtube vid of the mud under the V6 IM...?)

I see, that makes sense.
